' Specification of Letters Patent. Pat t d pl 15 1921 Application filed July is, 1918. Serial no. 243,826.?

T0 allwhom'zlt may concern: 7

Be it known that I, JOSEPH A. V. 'TURoK, a citizen of the United States, residing in ilmette, in the county of Cook and State of Illinois, have invented a "new and use ful Improvement in Calculating-Machines, of which the following is a specification.

This invention relates in general to adding machines and has more particular reference to adding machines wherein the add ing movements are induced from a suitable source of power and in response to the preliminary manipulation of appropriate keys so that the machine/is key responsive, the fingers merely manipulating the keys to govern each adding movement and in a multiple order machine to select the proper mechanism to IGCBlXG the adding movement. The invention contemplates the provision of a power-driven adding machine of compact construction and adapted for rapld, easy and certain manipulation.

An object of the present invention is the provision of a power driven adding machine, of the character above described, wherein the calculating actions will occur immediately upon or after the actuation of the keys by the operator so that the. machine may be operated as rapidly as the operator can manipulate his fingers.

An object of the invention is to provide a power-driven adding machine in which the application of power from a continuously movlng power member will be intermittently and positively applied to the ac cumulating mechanisms, and this as contradistinguished from the application of such power through frictional devices, although as the invention is better understood it will be manifest that features of it may be used with advantage in power'machine's employing frictional connection between the prime driving parts andthe driven members.

The invention has also for its object the provision of a power-driven apparatus having short and light key action to permit more rapid-manipulation by the operator.

A further object of the invention is the provision of an adding machine having these and other advantages which Will insure against improper key manipulation and this without the use of stops or other special devices provided for the purpose.

A still further object of the invention is the provision of zeroizing devices of sure operation with mechanisms of this character and so constructed and arranged that 'manlpulation of the keys of the adding mechanisms during a zeroizing operation Wlll neither interfere with the Zeroizing mechanism or make possible the jamming or injuring of any other parts;

A still further object of the invention is the provision of such Zeroizing devices and mechanlsm of the character described which byreason of its construction and operation protects the machine and all its parts from damage by "violent and improper actuation of the Zeroizing device.

Other objects and advantages of the invention will be apparent as it is better understood from the following description Fig. 4c is a partial detailed plan view with the casing removed, a portion of said view being taken above the top plate of the frame and a second portion being a section just therebeneath Figs. 5, 6 and 7 are vertical longitudinal sections taken respectively substantially on the lines 55, 6-6 and 7-7 of Fig. 1;

Figs. 8', 9 and 10 are fragmentary sectional views showing the relativeaction of certain cooperative parts to be more fully described;

Figs. 11 and 12 are partial transverse vertical sections taken substantially on the lines 11-11 and 12-12 of Figs. 5 and Fig. 4 respectively; l

Fig. 13 is a partial enlarged fragmentary view showing the provision of bearings for the continuously moving power members;

Fig. His a still further enlarged partial view of the same showing another section;

Fig. 15 is a partial vertical front to back secion showing the zeroizing mechanism; an

.Fig. 16 is a'perspective showing the rela In the machine embodying my present invention nowabout to be described continuously moving power. members are provided and these members are intermittently and upon desired occasion positively connected. with and actuate the parts driven by them.

The manipulation of the keys by the oper-' ator serves merely to determine the extent and location in proper ordinal or denominational places of the actuations causing the actuators and accumulating mechanisms to respond in movement in accordance with each particular key depressed by the operator, so that the machine may be said to be key-responsive.

For the purpose of illustrating the invention, I have shown on the drawing a machine in which it is embodied. Theworking parts are mounted within a casing '25 of any usual or preferred construction, through the top of which extend the key stems 26, each carrying a finger button27, said button and stem constituting a digital pin, upon which suitable indications, as numerals ranging from 1 to 9 with their complements, are provided. The operative parts are carried in a frame located within this casing and consisting of skeleton plates 28 disposed between the denominational or ordinal sets of mechanisms and at each side of the machine within the casing walls and tie rods or bars 29 are suitably arranged to connect said plates rigidly together and in certain instances to afford bearing pins or shafts for the moving parts.

A sub-top plate 31 (best shown-in Fig. 4) is securedto the casing just beneath the top plate so that when the casing is taken off the keys will come with it and expose the internal mechanism. The keys are arranged in orders and denominations, each order or denomination extendingfrom the front to the rear, and, as stated, the key stems extend through the top of the casing. Each key stem 26 is rectangular in cross section and is of relatively short length. A vertical slot 32 (Figs. 11, 12 and 16) extends from its lower end upwardly, providing two legs 33 and 34, one of which, 34 (the one at the left viewing'the front of the machine), is somewhat wider than the other, 33. The lower ends of each of these legs respectively extend through openings or slots 35 and 36 in the sub-top plate 31, so that each key stem is guided in its movement by the top of the casing and the sub-top plate 31. Springs 37 are provided to hold the keys in elevated position, one end of each spring taking into a slot or recess 39 in the narrower leg. When a key is depressed the two legs 33 and 34 of its stem are moved downwardly together through the openings 35 and 36 and arrange the mechanism for adding actuation, which occurs almost instantly.

. The parts and devices of the several delel and movableabout their pivotal axes to permit the bar-44 to have a longitudinal re ,ciprocating movement. A spring 45 fixed at one end to a lug 46 on the forward arm 41',

and at the other to a lug 47' on the under side of the bar 44, tends to move the arms 41 and 42 forwardly in the machine about their pivotal axes and to impart forward longitudinal motion to the bar 44. The top of the bar 44 is provided with a horizontally extending flange indicated at 48 in Fig. 4, which flange 1s cut away at intervals at 49 to provide spaced openings adapted to be disposed beneath the key stem when the bar is in re-- tracted position, and a plurality of stops or I lugs 51 extend out beyond the flange 48. When a key is depressed its leg 34 moves down through the appropriate opening 49, whereupon the bar 44 is permitted to move forwardly under the action of its spring 45, the portion of the flange 48 rearward of the opening 49, through which the leg of the key extends, passing through a slot 52 provided for the purpose. The bar 49 moves forward until a lug 51 engages the stem. The several lugs 51 are arranged rearwardly of the recesses at different distances, to provide a differential motion for the bar 44 in amount determined by the particular key of its order manipulated. It will be noted that the lug 51 back of'the recess 49 at the left is nearer the recess than the similar lug back of the recess 49 at the right. In the first instance the companion key is the 1 key and in the latter instance the 9 key.

It will be noted that the bar 44 is con-- nected by a link 53 with one end or arm 54 of a skeleton lever 55 pivoted upona cross rod or shaft 56. This lever is a segment lever that actuates the accumulator and has an arm 57 extending forwardly, which carries a toothed rack or segment 58, which actuates the accumulator. As the bar 44 moves forward, which occurs upon manipulation of a key of its order, the link 53 moves forward I also and the rack 58 swings downwardly in an idle stroke, the amount of this movement being determined by a particular key depressed. That is to say, the movement is terminated when the appropriate lug 51 engages a key stem. A spring 59 fastened at one end to a lip 61 on the lever 55 and at the other end to a rod 62 extending across the machine aids the movement and reinforces the action of the spring 45. The bar 44 is normally retained in position to hold the rack and arm or segment lever 55 elevated by a latch 63 pivoted upon a fixed rod 64 in the frame of the machine and engaging over a stud 66 carried by the bar 44. A spring- 67 secured to a tail 68 of the hook or latch 63 and to a suitable part of the framenormally pulls the latch downwardly in clockwise direction (viewing Fig. 8) and into engagementjwith the lug 66. This latch is adapted to be released at each depression of a key by a mechanism to be now described.

A release bar 69 is provided beneath the legs33 of the keys of each order and pivotally connected to yokes 71 and 72 pivotally mounted respectively upon cross rods 7 3 and 64 at the front and rear ends, each yoke having a perforation in its main part through which the rod passes and havin wings 71 and 72' extending out at the side and returning upon themselves, the return portion being perforated also for reception of the rod. A lower bar 74 also connects the yokes and this bar is connected by a spring 75 with a rear yoke 72, said spring and the bars and yokes being so arranged that the spring tends to swing the bar 69 upwardly. The

release bar 69, yokes 71 and 72, and the lower i I be later described.

bar 74 are thus so arranged that the bar 69 may be lowered and retained in parallelism with its normal position and the yokes have a 'pin and slot connection 80 with the release bar for limiting the movelnent under key pressure. The win 72 of the yoke 72 is disposed immediately beneath and in contact with the latch or hook 63. The pivotal connections between the bar 69 and the yokes 71 and 72 are rearwardly of the axes of pivotal movement of the yokes and in almost horizontal alinement with them, so that when a key is depressed the bar 69 has nearly a true downward movement. swings the yoke 72 forwardly and lifts the wing 72 to release the latch. During this time the key is moving on down and when the latch is released the slot 52 in the leg 34 of the key is in registration with the flange 48 on the bar 44, which flange now moves into the slot of the key, holding it down until the bar 44 is returned to normal position at the end of the adding movement, as will The difierential bar 44 continues to move forward until the appropriate lug 51 engagesv the side of the key stem and the machine is then set to have the action of the continuously moving power .members now about to be described, it being understood that the segment lever has moved down an amount determined by the particular key of the order manipulated and the adding operative movement is the return or upward movement of'the segment lever.

This" extends transversely of the machine at the rear and has bearings at 92 in the frame of the machine, asindicated in Figs. 13 and 14. The bearing used in the present instance is a wood bearing saturated with some lubricating material and indicated at 93. The wooden portion or hearing proper is provided on its outer surface with a dovetail shaped projection 94, which is embraced from one side by one part 95 of a bearing housing and at the other by a second part 96, said bearing hous'ing part having undercut flanges or ribs 97 engaging be neath the slanting portions of the dovetail projection. The two housing parts are threadedly connected at 98 and one of them, 95, is provided with an upstanding flange 99 adapted to be disposed in contact with a part 101 of the frame. Two collars, 102 and 103, are also threaded onto the part 95 and against the opposite side of the frame member to lock the bearing in the frgime. This form of bearing is used in the preent instance because of the need of providing an easy running, substantially frictionless bearing without the aid of a lubricant, which might ooze out upon the other parts of the machine or through the frame.

The shaft 91 is provided at its left-hand end with a crank 104 connected to a link 105, which in turn is connected to a crank 106 upon a shaft 107. By reason of this crank connection reciprocating or oscillating movement is continuously imparted to the shaft 107 and it is from this shaft that direct production of the adding movement is ac-- extends upwardly and in the oscillating Y movement of the shaft is thrown forward and downwardly. This arm carries a dog 111 pivoted at 112 on the arm and having a tail 113 above a stop pin 114 against which it is normally held by a spring 115. Under certain conditions when the arm 108 (Fig. 8) is moved in a clockwise direction it engages a tail 116 of a pawl 117 pivotally connected at 118 on the segment lever or arm 55 and spring-pressed in a clockwise direction, viewing Fig. 6, by a spring 119. The dog 117 engages in one of two teeth 121 and 122 in theupper end of a swinging bracket arm 123, as best shown in Figs. 8-10, which arm is pivoted at 124 on the segment lever. A driving arm 125 is pivoted on the bracket arm 123, which, as will be later described, is positively and directly engaged to actuate the segment lever when the segment lever has been lowered for an o erative return stroke. The tail of the brac et arm is conby a spring126 with the segmentlever, such sprlng tending to move the armsuitable lugs on the two arms to in a counter-clockwise direction. A'spring 120 is provided aboutthe pivotal connection of'the driving and bracket arms and engages ress the drivin arm in a 'counter-clockwlse direction- (Fig. 5), movement inthis direction being limited by the pivot pin 124 on the bracket arm which engages the right-hand end of the driving arm. The dog normally engages the forward tooth 121, as shownin Fig. 8, holdingthe arm elevated.

Viewing Fig. 8, it will be noted that the projection or arm 1'09 on'the shaft 107 is provided with a driving pin 127 and in the oscillation of the shaft 107 this pin 1s swung in a counter-clockwise direction in its operative stroke. The arm 125 normally rests above the arc of travel of the pin 127 and is adapted to be operatively'arranged for engagement therewith by the shifting of the pawl 117 from the lower notch 121 to the upper notch 122 under the action of the stop 111. This action will be seen by comparing rFigSJS- and 9. The segment lever 55 when in upper raised position holds thepawl117 outof the path of travel of the stop 111, so

i that in: the mechanisms associated with the late d tolower the segment levers to opera-.'

banks of keys which have not been maniputive position no action of the pawls 117 is produced by oscillation of the shaft 107.

lVhen, however, a key has been depressed and the segment lever swung downwardly a corresponding or desired amount, the tail 1 116 of the pawl is moved into position to be engaged by the dog 111 to move the pawl out' lowered in response to the lower numeral keys, the arm 125 is provided with a tail 131 adapted to move down upon the pin-127,

and under certain circumstances acts as a guide to insure'engagement of thejaw 130 i of the pawl with the pin 127. After oscillation of the arm 108 on the shaft to set the pawl 122 the shaft starts a movement in the reversedirection,'swing1ng the arm 109 and its pin 127 ina counter-clockwise direction,

viewing Figs. 8, 9 and 10, engaging the jaw of arm 125 and moving the segment lever up to its normal position, which movement .of the segment lever accomplishes the adding movement in the accumulator, as will be presently described. As the .segment lever.

r'eturns'to normal position the other parts, 2'. e.-'the bars 44 and 69 and associated parts, are also returned to normal position and the latch 72 reengages the projection 66. After these-parts are restored the pin 127 has a slight further movement which is enough to swing the arm 125 and the bracket arm 123 about their, pivotal centers and against the action of the springs 120 and 126, permitting the pawl to rengage in the notch 121.

The segment 58 of the segment lever is in continual mesh with the pinion 141 upon a pinion shaft 142 extending across the machine and this pinion is connected by a ratchet 144 with a lantern wheel 143. The accumulator mechanism, which includes these last mentioned parts and the numeral wheels 1 15 and connecting parts, is in the present instance substantially that of the well-known comptometer, fully described in Letters Patent of the United "States No.

1,072,933 to Dorr E.-Felt, issued September ,9, 1913 and other patents to said Dorr E.'

Felt, and also inUnited States Letters-Pat ent No. 1,110,734, and 'alsomentioned in my co-pending applicationSerial No. 231,814,

filed May 1, 1918, for zeroizing mechanisms,

and need not therefore be described in detail. It should be mentioned, however, that the lantern wheel 143 has fixed to it a pinion 140, which is the first of a-chain of gears 145, 146 and 147 mountedrespectively on shafts 148, 149 and 151, which connect the lantern wheel with the numeral. wheel, the last mentioned gear, 147, being fixed to such numeral wheel, Suitable safety devices against overthrow and back-latch and mechanism for carrying are provided,which need notbe described here, except to state that the stops and'safety devices engage the lantern wheel and'that the carryingis actively done in the first instance from one order to the next higher by a spring 152 attached to the gear 145 and to an escapement driving mechanism indicated generally at 153 in Fig. 7. As the numeral wheels are advanced power is stored up on these springs, which, after a numeral wheel has completed a summation of advances of ten steps, is released to impart a single step advance to the next higher wheel,

Zero'izingis accomplished in the present instance in much the manner of my co-pending application mentioned, althoughit is believed that for certain purposes this zeroizing mechanism should be claimed in this specification with other associatedand cooperating parts. Zeroizing is accomplished in this machine quickly and without interferingwith the normal operations of the machlneby momentarily disconnecting the numeral wheel from the lantern wheel, which, as has been stated, feels the influence of the stops and which by reason of the adding actuation.

, pivotal movement about the bearing shaft 151. One of these frames is provided for each ordinal place and consists of a main at intervals, one adjacent each spring-held against a stop 165 downwardly extendingplate 155 having an outwardly extending wing 156, which is returned inwardly, as indicated in Fig. 5, providing a secondary part 157 having bearing on the shaft 151 and having an offset part 158 slidably engaged with the forward end of an appropriate skeleton main frame plate 28. The several ordinal frames are rigidly connected by cross rods 154 and in a measure by the shafts 148, 149 and 151, so that they may be considered to form a single framehaving a pivotal axis about the shaft 151. Zeroizing is accomplished in the first instance by a short forward stroke of the lever 162 extending without the frame and visible more particularly in Figs. 1 and'2. This lever is attached to a shaft 163 extending within the casing and uponthe shaft 163 is fixed an arm 164 (Fig. 15) normally by aspring 166'connected at one end to a lug 167 on the arm and at the other to a pin 168 on the right-hand side outer skeleton frame plate This arm 164 carries at its end a. roller 169 adaptedto engage a camface 171' on a swinging arm 17 2 pivoted at 173 on the side skeleton plate 28. The arm 172 is con. nected by a link 174 with an arm 175 loose upon a shaft 176 and bearing against an arm 177 fixed on said shaft, the arms 175 and 177 being so arranged that they constitute in effect a single member. Extending rearwardly from the shaft 176 and arranged ordinal or denominational set of mechanisms, is an arm 178 (Figs. 6 and7), which arm is connected with a curved link or'lever 179 having a sliding fulcrum upon across shaft 181. This lever carries a pin 183 at its end which engages a lever 182 upon a cross rod 184 carried by the swinging frames. Each lever 182 forms one member of a toggle composed of it i and a short arm 185 pivoted to one end of said lever 182 and pivoted also to a stud 186 fixed in the main frame of the'machine. The pin 183 ofthe lever 179 engageswithin a bifurcated end 187 of the lever 182 and movement of this pin swings the toggle from one of its toggle-locked positions tothe other. Viewing Fig. 7, it will be noted that springs 188 are secured at one end at 189 arm 193 fast on the shaft 176 at the lefthand side of the machine and the main frame.

In zeroizing the lever 162 is swung toward the front of the machine, swinging in a clockwise direction the arm 164 (viewing Fig. 15). This causes the roller 169 to ride downwardly over the cam face 171 and until it engages in a stop recess 195. This moveto a pin 194 in ment swings the arm 172 upwardly and to-' wardfthe left and through the link 174 imparts a forward movement to the arm 175. This movement of the arm 175 'causes the toggles to swing from the position shown in Fig. 15 upwardly at their toggle connection, permitting the springs 1 88'to swing the frame downwardly and outwardly sulficiently to detrain the gears and release the carrying springs from the restraining influence of the' stop devices on the lantern wheel and permitting the numeral Wheels under the unwinding influence-of said springs to return to zero position, where they are halted by the engagement of stops 201 upon the back of gear 145' with stops 202 which are swung upwardly into operative position by movement of the toggles and which need not be described in detail-in this application since they are completely described in my co-pehding application above-mentioned.

As soon as the lever 162 is released the spring 166 pulls back this lever on the arm 164 to normal position causing the roller 169 to move up and into engagement with a stop 203 at the upper end of the cam face 171 and by movement of the arm 172 in a reverse direction breaking the toggle locks which have been established upon the outward swinging of the frame. The spring 192, already mentioned, causes the shaft 176 to move over beyond the movement imparted to it by the action of the roller 169 on engagement with the stop 1950f the arm 17 2. and until the stop 204 engages the screw lug. or projection 205 on the main frame,

fering with the normal manipulation of the machine orrequiring the operator to wait until any predetermined relation of parts is established for his zeroizing. It will be noted that this zeroizing mechanism merely starts the forward and return movements of the swinging frame relying upon' yielding springs to complete such movements. A

I doubleacting ratchet 211 cooperating with teeth 21% insures complete movement of the zeroizing lever in both directions.

It will be particularly noted that in this -key-responsive machine the adding .01 accumulating mechanism is driven positively, and in instant response to the key settings,

- by, the continuously running power device that becomes definitely connected with such mechanism fora definitely delimited and never lag in beginning or slip back or bethrown ahead or be in any manner interrupted to the very end of its required amplitude' And this must be accomplished for constantly varying measures of adding movement, and separately in each of the many ordinal places of the machine, and always at a tremendous velocity imparted to mechanism that is necessarily extremely light and fragile, and notwithstanding the varying inertias involved in driving the driven mechanism for varying distances in each ordinal place and for varying numbers of'the many ordinal places in the machine.

The power must not only be continuously running but 'also great enough to pick up instantly any of the varying loads that may be placed upon it, and yet it must not impose any frictional or other wear'or tear upon the light and fragile mechanism that it is intermittently and abruptly engaged with and disengaged from. The difficulty of providing such positively acting driving devices and connections is peculiarly great in such a key-responsive adding machine, in which the adding mechanism must respond instantly, and with extreme rapidity, to the lightest and swiftest play of the operators fingers on the keys.

It is thought that the invention and many of its attendant advantages will be 'under stood from the foregoing description, and it will be apparent that various changes may bemade in the form, construction and arrangement of the parts without departing from the spirit and scope ofthe invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
